[TheForge] propane forge - plumbing size vs flow?

[Jerry Frost]

I run up to 4 3/4" burners in my forge and supply them with a 1/4" manifold 
supplied with a 3/8" rubber hose. The final feed to the burners is 1/8" 
copper.

One 1" burner is about the same heat output as two 3/4" burners. The heat 
will be more concentrated so if you want even heat over the chamber use the 
3/4"ers and space them evenly.
